The South Carolina Department of Revenue fell victim to a cyberattack that resulted in the theft of 3.6 million Social Security numbers and the details for 387,000 credit and debit cards, Gov. Nikki Haley announced on Oct. 26.

Haley suggested that all who have filed a tax return in South Carolina since 1998 take steps to protect their identity and monitor their credit accounts. Those who have issues because of the incident will be assisted by the state, Haley said.

"This is the responsibility of the state to protect the taxpayers," she added.
